Q: have a france sim card but my phone is blocked, how do I unblock it?

hi, you'll need to contact your previous service provider (the one from who you got the iPhone) and ask for them to send you a code to unlock it.

It might cost you calling fees to call to your originating country, especially since service providers have special phone numbers, so you might want to ask a relative to call it for you, but you will need to give that person the phone's EMEI. you can find this number in the iPhone's settings.

P.S: Je parle Français si ça peut aider

and ask for them to send you a code to unlock it.

Don't post such rubbish

iPhones DO NOT USE A CODE

contact the Carrier who currently has a lock on your iPhone and find out their terms etc for unlocking indeed whether they do offer to unlock iPhones

Thisd is the process once you have contacted them
